Material and Methods: The patients in treatment of gastrointestinal decompression cured by our department from January 2013 to May 2015 whom were divided into 2 groups...

Phenols represent one of the most important classes of environmental chemicals. Most of them may cause serious public health and environmental problems. The present work is to develop an effective QSTR model for acute toxicity, a toxicological endpoint of Phenols. We calculated various descriptors and...

By testing fresh human red blood cells (RBCs), the morphology of human RBCs in different gravity fields was observed by SK2109P microscope. And the death rate of RBCs in different gravity fields were counted Results show that: RBCs can endure a certain gravity field. RBCs barely died under gravity fields...

Acridine orange (AO) and ethidium bromide (EB) are two fluorescent dyes for cell nuclei staining. The nucleus images by these two staining can make it easy to differentiate white blood cell (WBC) from red blood cell (RBC). We applied this principle to the white blood cell count by hemocytometer and this...

This paper aims at studying the efficacy and safety of flexible ureteroscopic holmium laser lithotripsy for treatment of kidney and upper ureteral calculi. Methods. The duration of operation, postoperative complication, postoperative calculus clearance rate of this surgery were analyzed based on 58 patients...

Cell surface display of target proteins has been widely used in biotechnology and industry. In this study, cell-wall binding domain (CBD) from Listeria phage endolysin A500 was fused with anchoring domains of YadA and OmpA, respectively, in Escherichia coli, aiming at binding of E. coli cells to Listeria...

For the sake of developing fish skin gelatin and CaCO3 composite films with antioxidant activity, different concentration of carnosine was added to it. In addition, the mechanical properties, optical properties, surface topography, anti-microbial activity, antioxidant activity and preservation effect...

In recent years, the methods with a generalized hidden Markov model have gained significant application and development in gene prediction, which is predicting the location and structure of genes in genomic sequences, and produced an army of remarkable programs, such as Genie, GENSCAN, AUGUSTUS, etc....

Selenium (Se) is an essential nutrient for humans as it plays an important role in anti-hyperglycemic and antioxidant activities. The objective of this work was to evaluate anti-hyperglycemic and antioxidant activities of Se-enriched mycelium polysaccharides. The Se-enriched mycelium polysaccharides...

Poly (β-L-malic-acid) (PMLA) is a sort of polyester and absolute biodegradable material. PMLA is a new type of nontoxic macromolecule material and with favorable biodegradation and biocompatibility. PMLA has extensive applications in the areas of pharmacy and medical industry. Application foreground...

Two symmetrical dinucleoside pentaphosphates, Up5U and Cp5C, were synthesized via the activation of the P (V)–N bond. The key nucleoside phosphoropiperidates intermediate were obtained by a redox condensation method. The reaction of the phosphoropiperidate with uridine and cytidine tetraphosphate in...

To understand how S-adenosylmethione (SAM) fluctuates in normal and cancerous liver cells, we developed novel methods for measuring methionine adenosyltransferase (MAT) activity and SAM. This method integrated MAT-catalyzed reaction and immunoassay that specifically and quantifies product SAM. IHC, IF...

Coagulation factor XII (FXII) is a multidomain serine protease that is the starter of intrinsic coagulation pathway. FXII deficiency and clinical hemostasis are not associated with bleeding, so investigators have not considered FXII important in physiology for a long time. In seeking explanation for...

In this paper, we use the sliding mode control based on high gain observer to control the concentration of Polydatin in the liver of SD rates. Through data processing and with the help of the nlinfit function in MATLAB, we take a fitting analysis by using the Polydatin distribution data in SD rats’ liver...

The aim of the paper was to study the effects of Polyphenolic extract from involucres of Castanea mollissima Blume (PICB) on IEC-6 cell proliferation and growth and antioxidant status. The IEC-6 heat stress model was established and IEC-6 cells of control group and heat stress group were treated with...

Bacterial cellulose (BC) shows good potentiality as active packaging material. However, bacterial cellulose itself has no antimicrobial activity to prevent microbial contamination. To achieve antimicrobial activity, -poly lysine ( -PL) was incorporated into BC by immersing BC in -PL solution. Investigations...

The Balb/c 3T3 cell transformation assay (CTA) is presently undergoing extensive pre-validation testing but its potential for routine chemical screening remains to be fully exploited due it being more costly and more time consuming than other CTAs. To downscale the assay 24-well plates were used to score...

To establish an effective model for cellular senescence, human embryo lung fibroblast cells (MRC-5) were cultured in D-galactose (D-Gal) medium respectively, as control, same concentration of D-glucose (D-Glu) was used. Decrease in cell proliferation, increase in senescence associated -galactosidase...

Trichloroacetic acid (tca) makes macromolecular peptides expose more hydrophobic groups and have precipitation effect. It’s widely used in the desalination and concentration of protein and peptide. This experiment use the alkaline protease enzymolysis the soybean protein isolated and makes the products...

The hanger tension is crucial in arch bridges, and the fundamental frequency of short hangers is significantly affected by the flexural rigidity. In order to measure the hanger tension considering the flexural rigidity, the Additional Mass Method (AMM) is applied. The tension and flexural rigidity can...

At early stage and late stage of cellular reprogramming the transgenes arouse two waves of transcription and epigenetic abruptly, while it is relatively quiet in intermediate stage. In this paper we analyzed the gene expression and chromatin modification data at different time point of mouse embryonic...
